Hi, I've been playing the game for a bit of time now and I've encounter an issue while playing : the key control from the keyboard suddenly stops working, or some sort of lag after 5 to 8 seconds of no response. After that I can play a while then the process repeats itself. I've been trying to rebind the keys but it doesn't help.

I'm playing on the 1.32 version of the game
My OS is Windows 8.1
Intel Core 7i-4710HQ
NVIDIA GeForce GTX 970M

I hope someone can help me. I've search this type of issue on the forum without results.
Thank you!

Well, the first things to try are reboot your computer and renew any batteries you may have in your keyboard if applicable, try a different keyboard if possible. Start at the simple things and work up.

I've used diferrent keyboard, wireless and wired. In the case of the wireless ones the batteries were all good. I've rebooted my computer, that helped but after 2 hours of gaming, the same issue came back again... I've been unplug and replug the wired keyboard, reset the default keybinds ingame... The issue is comming around 1 to 2 hours of gameplay then goes back off and on.

Did you try to use a different USB port? Is W3 the only game in which you experience this issue?

Hey there Sarafan, well I got the same issue with Witcher 2. I've got the issue in the end game. I've research this problem for this game and turns out it was a big deal for this game. Lots of players having issues. Many says to reset de default settings of the keybinds.
I will try a different USB port. Thank you.
